  1. PSF2_CORR - The point-spread function correction that may have been applied to extrapolate the corrected count rate from 12 to 35 unbinned pixels, defined by (corrected counts at 35 pixels / corrected counts at 12 pixels) * 100. This correction is presently only done for the UV filters, where the wings of the psf extend out a long way.
  2. MAG The instrumental magnitude computed using the corrected count rate and using the appropriate calibration constants for the filter.
  3. MAG_ERR The error in the computed instrumental magnitude.
